3 2.3 Transmitter / Sensor Location Prior to the installation process, a location plan for placing the transmitter and sensor should be developed. Factors such as accessibility, air movement, gas density in relation to air, emission sources and environmental variables affect correct sensor and trans...

4 2.4 The ECO-A-X Enclosure The ECO-A-X enclosure is an Aluminum or Stainless Steel explosion-proof (NEMA 4X) enclosure as shown in Figure 2-2. Table 1 : ECO Sense (ECO-A-X) housing and sensor dimensions ( A through J ) in Inches and mm Table 1 : (cont’d) ECO-A-X Transmitter & sensor I J in mm i...

5 WARNING : Qualified personnel should perform the installation according to applicable electrical codes, regulations and safety standards. Insure correct cabling and sealing fitting practices are implemented. Also, never install the sensor pointing upwards. 2.5 System Design Specifications Supply V...

6 ECO-A-X Transmitter Board Terminals Note: In Table 3, TB1 Terminals (Power Terminals) are non-polarized; if (+) 24VDC is connected to TB1 bottom terminal, and (-) 24VDC connected to TB1 top terminal a loop current of 4-20mA would still be obtained. Sensor separation Since the sensor must be locate...

7 SECTION 3 – INITIAL START-UP 3.1 “Transmitter Configuration” Menu Figure 3-1shows the ECO-A-X XMITTER CONFIG menu used to activate channels, precisely calibrate 4-20mA outputs and set time / date. Its menus are set at the factory and typically not needed by the user . To access from any data displ...

8 SECTION 4 – OPERATING INSTRUCTIONS 4.1 Routine Sensor Calibrations Calibration is the most important function for ensuring correct operation of the ECO-A-X. The CAL MODE (flow chart shown in Figure 4-2) is designed to make calibration quick, easy and error free. A successful ZERO and SPAN calibrat...

9 Calibration Steps Use the following step-by-step procedure to perform ZERO and SPAN calibrations. 1. To enter the CAL MODE activate the DOWN / CAL key with the magnet and within 5 seconds activate the EDIT key. 2. Using the Cal-Cup, apply clean ZERO gas (air) from canister or be sure there is no b...

10 4.2 ALARM OPERATION The ECO-A-X has front panel LED indicators for Alarm 1(ALM1), Alarm 2(ALM2) and Alarm 3(FAIL). With 2-Wire 4-20mA operation, to conserve power, alarm LED’s only flash during alarm events. 4.2.1 ALARM 3 – UNDERSTANDING FAULT / LEVEL OPERATION The “A3”(FAIL) alarm is typically d...

11 SECTION 5 – SETUP MENU CONFIGURATION 5.1 Menus Database Configuration All ECO-A-X configuration variables are stored in its menu database. Many menu items will contain default values from the factory and require changes to better match a user’s particular application. ECO-A-X menus may be configu...

12 items/sub menus. Use EDIT key to display the cursor, then activate UP / DOWN key to change that character, activate NEXT to move the cursor, then activate EDIT key again to load the new item and remove the cursor. Activate NEXT to back out of the sub-menu. To view SETUP PAGE 2 , activate the DOWN...

13 Linearization Data allows nonlinear signals to be linearized by entering the correct curve into the ECO-A-X (Figure 5-4). If Linearize is set for NO, the CURVE POINTS menu data is not used and no linearization is applied. When YES, the CURVE POINT entries are used and a straight-line approximatio...

17 5.10 SYSTEM SECURITY: The SYSTEM SECURITY menu offers two levels of protection. A LOW level allows CAL MODE sensor calibrations but requires the 4-digit Pass Code prior to altering menus. HIGH level locks the entire menu database and the CAL Mode until the correct Pass Code is entered. LOW and HI...

18 SECTION 6 – HOW TO RETURN EQUIPMENT A Material Return Authorization number is required in order to return equipment. Please contact Net Safety Monitoring at (403) 219-0688 , before returning equipment or consult our Customer Care Department to possibly avoid returning equipment. If you are requir...

19 Appendix Appendix A: Electrostatic Sensitive Device (ESD) Definition: Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic charge caused by direct contact or induced by an electrostatic field. The most common cause of ESD is physical contact. Touching an object can c...
